need someone to go over the genera and place them on a firmer founda- 

 tion and properly correlate the species. The genera of the world would 

 have to be taken into account to do this properly. 



Dr. Scudder's genera are often based on flimsy characters or none at 

 all. The common Thecla melinus is put into Uranotes. This genus 

 differs from the others in having "the inner transverse stripe on under 

 surface of hind wings with only shallow or zigzag indentations." Habro- 

 dias ( Thecla griinus) " with tail of hind wings triangular." 



Some divisions in Thecla are "hind wings tailed" and "hind wings not 

 tailed." This in some cases would place one species in two genera. In 

 other cases genera are based on color alone. Many genera not used in 

 the list have been proposed. Why would it not have been logical to 

 have used them all ? Dr. Dyar has put into the synonymy many de- 

 scribed varieties based on color, etc. Perhaps he is right in the individ- 

 ual cases, but he is certainly wrong from a comparative stand point. All 

 should go or none. For instance, he sinks fuinosus a color variety of 

 Danais plexippus, and describes as new, altaurus as a variety of Parnas- 

 sius clodius, because it has yellow spots instead of red. 



The list shows many incongruities. Let us hope that bringing them so 

 prominently into notice will have a tendency to cure the evil. H. S. 



In the Journal of the Association of Military Surgeons, Vol. .vii, No. 

 2. pp. 84-107 (February, 1903), C. S. Ludlow, M.Sc., publishes a paper 

 entitled : " Classification, geographical distribution and seasonal flight of 

 the mosquitoes of the Philippine Islands." The author describes as new 

 species, Anopheles pseudobarbirostris and A. philippinensis. The paper 

 is illustrated by figures showing structure, and has many interesting notes 

 on the various species. W. J. F. 



Doings of Societies. 



A meeting of the Entomological Section of the Academy 

 of Natural Sciences of Philadelphia was held Jan. 22d, Mr. 

 Philip Laurent presiding. Fourteen persons present. Mr. 

 W. D. Denton, visitor from Wellesley, Mass. Dr. Calvert ex- 

 hibited and made some remarks on the Odonata described in 

 the February NEWS. Mr. Rehn exhibited the roaches belong- 

 ing to the genus Homoeogamia. The box contained all the 

 species, including a recently described one from New Mexico. 

 The type was unique until the speaker and Mr. Viereck had 

 taken eleven specimens. Mr. Bradley again referred to the 

 specimens of the family Mymaridse and decided that the genus
